To all whom it may concern.'

. Be it known that LCHARLES E. YARIAN, a citizen of the United States,residing at Galion, in the county of Grawford and State of Ohio, haveinvented certain new. and useful Improvements in Traversing Hoists; andI do hereby declare the following to be a. full, clear, andexactdescription of the invention, such as will enable others skilled inthe art to Which it appertains` tomake and use thesame.` a a 4 Thisinvention relates to traversing hoists and more particularly to `thatclass of hoists designed to be used in handling coal, sand. gravel,crushed rock and materials of similar description. l

lt has been' found in practice that dealers in the above mentionedmaterials, who receive these products in carloadlots, suffer seriousinconvenience in unloading and stor-` ingthe same, owing to railroadregulations relative to the location of the storage bins of the dealerwith respect to the companys tracks. As switches and sidings are onlyobtainable at considerable cost, and as'this cost is in proportion tothe length of the siding, asidingr of minimum length is greatly tobedesired. 1 e y With these facts inmind, it is the object of thisinventionto provide means for `unloading material suchl as coal, crushedrock, sand, gravel, etc., from the car in which it is delivered to thedealer, conveying said ma` terial to its proper storage bin, said meansbeing adapted to receivethe various mate` rials at the same point on thesame siding, and transfer" them to their respective bins, which may beplaced at any convenient location;

With this and other objects in view that may more fully hereinafterappear,the invention contemplates the provision of a plurality ofstorage `bins which are preferably located in a line at right angles tothe tracks of the siding, but through proper arrange ment of the parts"hereinafter described.wtl1e bins may be placed in any convenientlocation. The invention further comprises a traversing hoist providedwith a novel cable clamping device by which the `conveyer` bucket andits contents may be raised to any desired height priorto its journeytothe bin, and retained, if desired, at" this height throughout itscourse, being automatically dropped-atits bin by a trip located abovesaid bin 0n the overhead track.`

V Onev embodiment of my inventionis hereinafter fully described andillustrated in the accompanying drawings, and more particularly pointedout in the appended claims, it being fully understood that" such changesin size and proportion oflparts and in minor details of constructionemaybe made as clearly fall Within the scope of the appended claims withoutdepartiiig fro-1n the spiritor sacrilicing any of` thegadvantages oftheini'fention.` y y ln Vthe accompanying i drawings `Figure 1` is aside elevation of the over-` head track *with "the traveling carriagemounted therein, and the conveyer bucket suspended fromlsaidcarriage. e

Referring more l particularly "to the accompanying drawings l and theembodiment of my invention disclosed therein,`

4l() designates `an, overhead track `of `any suitable materialsupportedby any `preferred means, such as upright membersflll, and aplurality `of overhead hangers 42, said track being pOVdedfWitbaplurality of longitudinal grooves 43 on its upper face designed toreceive the rollers or wheels of the traveling carriage, as wlllbehereinafter described. i

The `overhead track is carried above the a mounted uponfthe undersideofthe track bv means of "suitable" yokes or bearings 45,

whichareadaptedtoreceive a pintle 46 upon which thetrips arerotatably`mounted. Atthe points oir the track where is desired to mount saidtrips, the track is reeessed as at 47, said recess having a cylindricalduct 48 communicating with the upper face of the track.

The trips 44 are provided on their upper faces 49 with a resilientmember 5l secured to said trips by screws 50, said screws being providedwith eyes 50a designed to receive the. rods 52, said yrods extendingupward through the ducts 48 and extending slightly above the upper faceof the track,

.and having at their upper ends an eve 53 designed to receive a cable54. The resilient members 5l are designed to engage the upper faces 55of the recesses 47 to return the trips 44 to their outward position.

The traveling, carriage, designed to ride upon the overhead track 40,comprises a substantial frame 60 provided with a plurality of wheels orrollers 56 suitably journaled on pintles 57, a separate and distinctpintle being provided for each roller, as clearly seen in Fig. 5. Thepurpose of this mounting of the wheels is to provide for the passage ofthe overhead hangers 42, and the cable 54 between the rollerskpositioned on opposite sides of the frame, when the carriage is mountedon the track as shown in Fig. 5. .The hangers 42 may be provided withsuitable apertures 58 to receive the cable54.

Suspended from the carriage frame 60 by vertical members 59 is a frame61 carrying a plurality of pulleys 62 and 63, said pulleys beingrotatably mounted on suitable pintles 64 carried by said frame. e

Suspended vfrom the frame 61 by a plurality ofcleats of equal length 65,is a frame 66. The cleats 65 are pivotally mounted to the frames 61 and66 by suitable pintles 68, thereby allowing the frame 66 longitudinalmotion with respect to the frame 61, and at the same time retaining theframes in a po` sition parallel to each other.

Pivotally mounted on the frames 66 and 61 is a cable clamping device,best seen in Figs'Q and 3. The frame 61 terminates at one end in`enlarged portions 69 between which is rigidly positioned a grippingblock 70, vsaid block being'provided with a plu rality of teeth orcorrugations 71. Pivotally mounted between the opposite sides of theframe 66 upon pintles 72 is a pivotal jaw 74 having a corrugatedfacev74el to coperate lwith the corrugated face 71 of the gripping block70, to clamp a cable passed between said faces, as hereinafterdescribed. This construction -is vclearly shown in Fig. 3, where isdisclosed a plurality of 1egs'73 carried by the jaw 74 and yby whichsaidj aw is attached to the frame 66. AsV shown in Fig. 3, the jawextends upward between the opposite sides' of the frame 61 and isrotatably connected tol iframe 61 by a pintle 75, said pintle carrying asuitable pulley 76.

The pulley 63 of the frame 61 is provided on its outer periphery .with aplurality of teeth 77, designed to engage a bar 77 carried by the legs73 of the jaw 74, when said jaw is rotated on pintle 75 by alongitudinal movement of the frame 66 as will be hereinafter fullydescribed.

Suspended from the traveling carriage by a suitable cable 78 fastened toa bar 79, carried between the opposite sides of the frame 61, is a frame80 from which is suspended a suitable conveyer bucket 87. The frame isshown provided with a plurality of pulleys 81 and 81a suitably journaledon pintles 82 carried by said frame. The cable 78 is led downward fromthe bar 79 through the pulley 81 upward and around pulley 62, thencedownward and through pulley S1". thence upward and. around toothedpulley 637 thence over the pulley 76 of the jaw 7i between the legs 73thereof and the faces 74a and 71 of the jaw and the gripping block,respectively, and thence by means of a swiveled pulley 83 to the drum ofa hoist.

The operation of the device is as follows:

The bucket having been lowered and filled in the usual manner is thenraised by applying power to the cable 7 8 to any desired height, and:when such height has been attained, power is applied to the cable 84,thereby communicating longitudinal movement to the frame 66 in thedirection in which the force is applied, causing the pivoted jaw 74 torotate on its pintle and comel into clamping engagement with the cable 73 passing between the corrugated faces 7 4 and 71, at the same timebringing the bar 77" into mesh with the teeth of the pulley 63,

thereby effectively lorking the same. Power is then removed from theVcable 78 and through the force applied to the carriage by means of thecable 84, the traveling carriage proceeds along the overhead track.

The pivoted jaw 74 is provided with an extended portion which terminatesin close proximity to` the underside of the overhead track, and is sopositioned as to engage the trips 44 mounted thereon. It is evident fromthe foregoing description taken in connection |with the accompanyingdrawings that the trips are s0` mounted as to permit of the free passageof the carriage in one direction, but will offer obstruction to itspassage in the opposite direction. Having this in mind, the carriage ispulled freely along the track until the desired storage bin is reached,above which is positioned a trip. The carriage is pulled past the trip,said trip being forced into its recess by the end of the jaw 74, andsaid trip being forced outward into its operative position by theresilient member 51. The carriage is then pulled back so as to bring theextended portion of the jaw into engagement with the vertical masonesface of the trip, thereby causing the jaw to be opened., the cable to bereleased,and the bar 77a to be drawn from engagement with the teeth 77of the pulley `(53, allowing the bucket to be lowered.

When the contents of the bucket have been discharged, the bucketisraisedto any desired height and a slight pull given to the cable 84e to clampthe cable 7 8 between :the jaw: 74 and the gripping block 70, andtobi-mg" the bar 77au into engagement with the teeth of the pulley 63,thus effectively locking thc bucket at the desired height. The cable 54is then pulled to draw the trips into their respective recesses, therebyallowing the carriage free lpassage along the track. "When the carriagehas passed the last trip before the one located above the loading pit,the cable 54 is released, allowing the trips to resume their operativeposition. The jaw 74 coming into contact with the trip, thus placed inoperative position, is opened and the cable and pulley released, asbefore described, and the bucket lowered for reloading.

Having thus fully described my invention what I claim is y 1. Thecombination with a track, ot' a carriage to ride thereon, a bucketsuspended from the carriage, means to raise and lower the bucket withrespect to the carriage, means carried by the carriage to retain thebucket at any desired height, and coperative means between the carriageand the track to release the bucket at a plurality of predeterminedpoints.
